I am in the begining stages of producing a conce0t drawing for the rental property.

A lawyer or CPA will handle all the filings for you, including obtaining your EIN, filing the SOI and BOI, and ensuring compliance with the California FTB.

I then went to the court house and filed a wrongful detainer.

As you know, cash flow comes down to how much you have to put in the deal, what it produces, and how your debt payment is structured. 

More than likely, the loan officer on your file either A) didnt know their own product very well, or B) glossed over this aspect in order to get the loan to closed due to a lack of integrity. 

That's the key component that is usually missing when I hear other entrepreneurs/investors say they don't like QBO.Something else to keep in mind is your entity structure and how your entities file tax returns.

Real estate investments (STRs, MTRs, live in flips) have produced my best returns by a good margin.

You could just have her file a Quit claim deed and leave it in your name only instead of an LLC.

And it is very straightforward to file these, so I would expect it to be well within the scope of any operator sophisticated enough to pull off an owner financed deal. 

I am filing a suit in Orange County Superior Court and along with reporting to following government entity.
